Below is the example of the Math cbrt() Method.

Hey geek! The constant emerging technologies in the world of web development always keeps the excitement for this subject through the roof. But before you tackle the big projects, we suggest you start by learning the basics. Kickstart your web development journey by learning JS concepts with our JavaScript Course. Now at it's lowest price ever!

• Example:
 ` `
• Output:
```cbrt of 16: 4
cbrt of 27: 3
cbrt of 0: 0
cbrt of -1: -1
cbrt of -27: -3
cbrt of Infinity : Infinity```

The Math.cbrt() method is used to find cube root of a number.
Syntax:

`Math.cbrt(x)`

Parameters: This method accepts a single parameter as mentioned above and described below:

• x: This parameter is a simply a number whose cube root need to be find.

Returns: It returns the cube root of the given number.

Below example illustrate the cbrt() method in JavaScript:
Example: Here cube root of 8 is calculated to 2 because when any 3 times repeated any number is present inside of the cube root then only one number is taken out as the value of the cube root.
∛8
= ∛2*2*2
= 2

```Input: Math.cbrt(8)
Output : 2
```

More codes for the above method are as follows:

Program 1: Errors and Exceptions, it is an error case because cube root of complex number can not be found that is why its parameter gives error.

 ` `

Output:

`Error: Invalid or unexpected token`

Program 2: Cube root of string can not be found that is why string parameter of the function gives NaN i.e, not a number. An only integer value can be used as the parameter for the function.

 ` `

Output:

`cbrt of a string: NaN`

Program 3: Whenever we need to get cube root of any number that time we take the help of the Math.cbrt() function in JavaScript.

 ` `

Output:

```Output : 5
Output : 2.8438669798515654```
